As an alternative you can also provide -o to keep each file name intact.
另外，还可以提供- o选项以保持每个文件名不变。
PVFS sends a request to the meta-data server (steps 1 and 2 in Figure 4), which informs the requesting node about the location of the file among the various I/O nodes.
PVFS向元数据服务器发送一个请求（图4中的步骤1、2），这会通知请求节点有关文件在各个I/O 节点上的位置的信息。
